Description

Technical Field

[0001] This utility model relates to the field of headlamp technology, specifically a lithium-ion headlamp. Background Technology

[0002] Lithium battery headlamps are portable lighting devices powered by lithium-ion or lithium polymer batteries. They are widely used in outdoor activities (such as camping, hiking, cycling), night work (such as maintenance, mining), or emergency scenarios. Currently, some headlamps and searchlights on the market use relatively traditional technologies.

[0003] For example, a combined lithium battery headlamp disclosed in the authorization announcement number CN220817556U includes a control box and a headband. One end of the control box is rotatably connected to a lamp cover, and a connecting ring is fixedly installed on the outer side of the lamp cover. A lamp cover is provided above the lamp cover. Two connecting blocks are fixedly installed on the upper end of the lamp cover. A connecting block is fixedly installed on the lower end of the lamp cover. A rotating shaft is slidably connected inside the two connecting blocks. The outer sides of the two rotating shafts are rotatably connected to the inside of the connecting block.

[0004] Although it achieves the goal of rotating the headlamp by rotating the shaft, allowing the user to rotate the second lampshade counterclockwise around the shaft during high-precision work, thus driving the second connecting block to rotate counterclockwise around the shaft, the second lampshade, with its reflective material inside, can focus the light, thereby quickly adjusting the intensity of the light and making the illuminated area brighter, improving the user's work efficiency. If the user needs to find tools during work breaks, the second lampshade can be rotated clockwise to facilitate finding tools or reduce the impact on oncoming people. The rotating rods one and two allow the user to press the rotating rods one and two to slide the two rotating shafts outward when changing the headlamp with different lampshade combinations, thereby removing the second connecting block from between the two rotating shafts and replacing it with different models of the second lampshade. This gives the headlamp a variety of different combinations, making it convenient for users to use in different working environments and for different tasks.

[0005] However, this does not solve the problems that existing headlamps of this type are generally not convenient to adjust the position for illumination, are not convenient to replace lithium batteries, affecting the efficiency of lithium battery replacement, and are not convenient to adjust the height to fit the user's head, thus affecting the adjustment range and the convenience of using lithium battery headlamps. Utility Model Content

[0006] The purpose of this utility model is to provide a lithium-ion headlamp to solve the problems mentioned in the background art, such as the headlamp's inconvenient adjustment of position for illumination, the inconvenient replacement of lithium batteries, which affects the efficiency of lithium battery replacement, and the inconvenient height adjustment to fit the user's head, which affects the adjustment range and the convenience of using the lithium-ion headlamp.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lithium-ion headlamp, comprising an elastic band and a U-shaped frame, wherein the elastic band is provided with a U-shaped frame on its exterior, and the U-shaped frame is provided with a C-shaped frame on its exterior. A battery box is installed on the side wall of the C-shaped frame, a reflector shell is installed on the side wall of the battery box, a headlamp cover is installed on the side wall of the reflector shell, and a bulb is installed inside the reflector shell. A first buckle is installed at one end of the elastic band, and a second buckle is installed at the other end of the elastic band. A fixing block is installed on the side wall of the elastic band. Multiple sets of through holes with equal spacing are provided on both sides of the C-shaped frame. A second threaded rod is movably fitted on both sides of the C-shaped frame, and the second threaded rod extends through the C-shaped frame and the U-shaped frame to their exterior.

[0008] Preferably, the surface of the second threaded rod is fitted with a nut, and the second threaded rod is threadedly connected to the nut.

[0009] Preferably, a switch button is installed on the side wall of the battery box, and a charging port is installed on the side of the side wall of the battery box away from the switch button.

[0010] Preferably, the battery box is provided with a battery sleeve on the outside, and an 18650 lithium battery is installed inside the battery sleeve.

[0011] Preferably, elastic locking blocks are installed on both sides of the battery case, and limiting blocks are symmetrically installed inside the battery case.

[0012] Preferably, a slider is slidably mounted on the side wall of the fixed block, a movable block is provided on the outside of the fixed block, and a threaded hole is provided on the side wall of the fixed block away from the slider.

[0013] Preferably, springs are symmetrically installed on the side wall of the external fixing block of the threaded hole, and the side of the spring away from the fixing block is in contact with the movable block.

[0014] Preferably, a first threaded rod is movably mounted on the side wall of the movable block, and the first threaded rod passes through the movable block and is threadedly connected to the threaded hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the headlamp not only enables convenient adjustment of the position for illumination and facilitates easy replacement of the lithium battery, thus improving the efficiency of lithium battery replacement, but also facilitates convenient height adjustment to fit the human head and body, increasing the adjustment range and improving the convenience of using the lithium battery headlamp.

[0016] (1) Tighten the two sets of second threaded rods to disengage the second threaded rods from the nuts, pull out the second threaded rods, move the C-frame a certain distance, and then pass the second threaded rods through the through holes on the surface of the C-frame and the U-frame. Connect the nuts and the second threaded rods with threads. When it is necessary to adjust the illumination angle, rotate the C-frame so that the C-frame rotates around the second threaded rod as the axis. The C-frame drives the battery box, the light cup plastic shell, the headlamp cover, and the bulb to rotate around the second threaded rod as the axis for illumination. After the adjustment is completed, tighten the second threaded rod. Under the threaded connection between the second threaded rod and the nut, the U-frame and the C-frame are squeezed and fixed to a limited position, which realizes the convenient adjustment of the position of the lithium battery headlamp for illumination, increases the illumination range, and improves the convenience of adjusting the position of the lithium battery headlamp for illumination.

[0017] (2) Squeeze the two sets of elastic blocks. Under the elastic support of the two sets of elastic blocks, the two sets of elastic blocks move towards each other. Under the limiting support of the limiting block, the two sets of elastic blocks separate from the limiting block, and the battery box and 18650 lithium battery are taken out and replaced. This realizes the convenient replacement of lithium batteries in lithium headlights, reduces the labor intensity of manual labor, and improves the efficiency of replacing lithium batteries in lithium headlights.

[0018] (3) Tighten the first threaded rod so that the first threaded rod is disengaged from the threaded hole. Under the elastic support of the spring, the spring will push the movable block outward, thereby increasing the distance between the movable block and the fixed block, so that the slider can slide on the side wall of the fixed block. When it slides to a suitable height, screw the first threaded rod into the inside of the threaded hole. Under the threaded connection between the first threaded rod and the threaded hole, the first threaded rod will drive the movable block to move closer to the fixed block and squeeze it. Under the support of the fixed block, the slider is limited and fixed, realizing the convenient height adjustment of the lithium battery headlamp to adapt to the human head, increasing the adjustment range and improving the convenience of using the lithium battery headlamp.

[0032] Example 1

[0033] Please see Figures 1 to 9 The present invention provides an embodiment of a lithium-ion headlamp, comprising an elastic band 1 and a U-shaped frame 2. The elastic band 1 is provided with a U-shaped frame 2 on its outside, and a C-shaped frame 13 is provided with a C-shaped frame 13 on its outside. A battery box 3 is installed on the side wall of the C-shaped frame 13, a light cup plastic shell 4 is installed on the side wall of the battery box 3, a headlamp cover 5 is installed on the side wall of the light cup plastic shell 4, and a bulb 6 is installed inside the light cup plastic shell 4. A first buckle 7 is installed at one end of the elastic band 1, a second buckle 8 is installed at the other end of the elastic band 1, and a fixing block 9 is installed on the side wall of the elastic band 1. Multiple sets of through holes 14 with equal spacing are provided on both sides of the C-shaped frame 13. A second threaded rod 15 is movably fitted on both sides of the C-shaped frame 13. The second threaded rod 15 extends through the C-shaped frame 13 and the U-shaped frame 2 to their outside.

[0034] Nuts 16 are fitted on the surface of the second threaded rod 15, and the second threaded rod 15 is threadedly connected to the nuts 16. A switch button 17 is installed on the side wall of the battery box 3, and a charging port 18 is installed on the side wall of the battery box 3 away from the switch button 17.

[0035] When using the lithium-ion headlamp, the external power supply charges the 18650 lithium battery 20 through the charging port 18. The elastic band 1 is placed over the head, and the first buckle 7 and the second buckle 8 are secured to fix the lithium-ion headlamp on the head. The switch button 17 is pressed to turn on the light. When the illumination distance needs to be adjusted, the two sets of second threaded rods 15 are turned. Under the threaded connection between the second threaded rod 15 and the nut 16, the second threaded rod 15 is disengaged from the nut 16. The second threaded rod 15 is pulled out, and the C-frame 13 is moved a certain distance. The second threaded rod 15 is then passed through the through hole 14 and the U-frame 2 on the surface of the C-frame 13. The nut 16 is then... The second threaded rod 15 is threaded to facilitate front and rear position adjustment. When the illumination angle needs to be adjusted, the C-shaped frame 13 is rotated, causing the C-shaped frame 13 to rotate around the second threaded rod 15 as an axis. The C-shaped frame 13 drives the battery box 3, the light cup plastic shell 4, the headlamp cover 5, and the bulb 6 to rotate around the second threaded rod 15 as an axis for illumination. After adjustment, the second threaded rod 15 is tightened. Under the threaded connection between the second threaded rod 15 and the nut 16, the U-shaped frame 2 and the C-shaped frame 13 are pressed and fixed, which realizes the convenient adjustment of the position of the lithium battery headlamp for illumination, increases the illumination range, and improves the convenience of adjusting the position of the lithium battery headlamp for illumination.

[0036] The battery box 3 is provided with a battery sleeve 19 on the outside, and an 18650 lithium battery 20 is installed inside the battery sleeve 19. Elastic blocks 21 are installed on both sides of the battery sleeve 19, and limit blocks 22 are symmetrically installed inside the battery box 3.

[0037] When the 18650 lithium battery 20 needs to be replaced, squeeze the two sets of elastic latches 21. Under the elastic support of the two sets of elastic latches 21, the two sets of elastic latches 21 move towards each other. Under the limiting support of the limiting block 22, the two sets of elastic latches 21 disengage from the limiting block 22, and the battery box 19 and the 18650 lithium battery 20 can be taken out for replacement. This realizes the convenient replacement of lithium batteries in lithium battery headlamps, reduces the labor intensity of manual labor, and improves the efficiency of lithium battery replacement in lithium battery headlamps.

[0038] A slider 12 is slidably installed on the side wall of the fixed block 9, a movable block 10 is provided on the outside of the fixed block 9, and a threaded hole 24 is provided on the side wall of the fixed block 9 away from the slider 12.

[0039] Springs 23 are symmetrically installed on the side wall of the external fixing block 9 of the threaded hole 24. The side of the springs 23 away from the fixing block 9 is in contact with the movable block 10. A first threaded rod 11 is movably installed on the side wall of the movable block 10. The first threaded rod 11 passes through the movable block 10 and is threadedly connected to the threaded hole 24.

[0040] When the height needs to be adjusted to fit the human head, the first threaded rod 11 is turned. Under the threaded connection between the first threaded rod 11 and the threaded hole 24, the first threaded rod 11 is disengaged from the threaded hole 24. Under the elastic support of the spring 23, the spring 23 pushes the movable block 10 outward, thereby increasing the distance between the movable block 10 and the fixed block 9, allowing the slider 12 to slide on the side wall of the fixed block 9. When it slides to the appropriate height, the first threaded rod 11 is screwed into the threaded hole 24. Under the threaded connection between the first threaded rod 11 and the threaded hole 24, the first threaded rod 11 drives the movable block 10 to move closer to the fixed block 9 and press it. Under the support of the fixed block 9, the slider 12 is limited and fixed, realizing the convenient height adjustment of the lithium battery headlamp to fit the human head, increasing the adjustment range and improving the convenience of using the lithium battery headlamp.

[0041] Work steps

[0042] Tighten the two sets of second threaded rods 15 to disengage them from the nuts 16. Pull out the second threaded rods 15, move the C-frame 13 a certain distance, and then pass the second threaded rods 15 through the through holes 14 and U-frame 2 on the surface of the C-frame 13. Thread the nuts 16 to the second threaded rods 15. When adjusting the irradiation angle, rotate the C-frame 13 so that it rotates around the second threaded rods 15. The C-frame 13 drives the battery box 3, the light cup plastic shell 4, the headlamp cover 5, and the bulb 6 to rotate around the second threaded rods 15 for irradiation. After adjustment, tighten the second threaded rods 15 to compress and fix the U-frame 2 and C-frame 13. Pinch the two sets of elastic locking blocks 21. Under the elastic support of the two sets of elastic locking blocks 21, the two sets of elastic locking blocks 21 move towards each other. Under the limiting support of the limiting block 22, the angle is adjusted. The two sets of elastic locking blocks 21 are disengaged from the limiting block 22. The battery case 19 and the 18650 lithium battery 20 are then removed and replaced. When the height needs to be adjusted to fit the head, the first threaded rod 11 is turned so that it disengages from the threaded hole 24. Under the elastic support of the spring 23, the spring 23 pushes the movable locking block 10 outward, thereby increasing the distance between the movable locking block 10 and the fixed locking block 9. This allows the slider 12 to slide on the side wall of the fixed locking block 9. When the slider reaches the appropriate height, the first threaded rod 11 is screwed into the threaded hole 24. With the threaded connection between the first threaded rod 11 and the threaded hole 24, the first threaded rod 11 drives the movable locking block 10 to move closer to and press against the fixed locking block 9. Under the support of the fixed locking block 9, the slider 12 is limited and fixed, thus completing the use of the headlamp.
